What happened
During the initial stages of a takeoff roll at Oradea Airport, an incident occurred involving the premature retraction of the aircraft's undercarriage. While the plane was still accelerating along the runway, the flight engineer, who was undergoing training at the time, moved the landing gear lever into the retracted position.
As a result of this action, the aircraft type lost its structural support from the wheels and settled onto its belly. The movement caused the plane to skid along the runway surface before eventually coming to a complete stop. Despite the severity of the impact with the ground, all 11 occupants were able to evacuate the aircraft without sustaining any injuries.
Findings
Investigations into the event concluded that the primary factor was the premature retraction of the undercarriage during the takeoff phase of flight. The incident resulted in significant damage to the airframe, rendering the vessel a total loss.
